On Friday, Keegan Bradley let a picture do the talking in his ongoing contention that the USGA and R&A ought to drop their plans to ban the anchoring of putter strokes and, therefore, keep long putters legal and valid.

Keegan Bradley took to Twitter on Friday to show us this photo of a golfer from many decades ago anchoring a putter to his body.

By now, we all know Keegan Bradley's stance on the issues of belly putters and the proposed anchoring ban.

On Friday, he let a picture do the talking in his ongoing contention that the USGA and R&A ought to drop their plans to ban the anchoring of putter strokes and, therefore, keep long putters legal and valid.

While walking through the clubhouse at Riviera on Friday, he ran across the photo posted above. As you can see, it shows a golfer clearly anchoring a putter to his body many decades ago. Looking closely, that flat stick doesn't exactly look like a long putter, but it is definitely anchored.

To golfers interested in the anchoring debate, this photo is a bit like an archaeologist discovering new fossils that indicate the presence of humans farther back in time than anyone had thought. Photos like this show that at least some golfers have been anchoring for many decades, if not centuries. That fact might or might not change anyone's mind regarding whether anchoring should be okayed or outlawed, but it certainly adds a new dimension to the debate.

When he posted the photo on Twitter, all Bradley wrote was, ''Picture in Rivera clubhouse. Early 1900's.''
